Chemical abundances as fingerprints of galaxy evolution
The evolution of chemical abundances in galaxies provides crucial information to study how they formed and evolved. Results in the Local Universe show that on average, star-forming gas-phase in galaxies have negative metallicity gradients and that flat and inverted positive gradients could be associated with galaxy interactions and gas accretion. As a function of redshift, there seems to be an increase of the fraction of inverted metallicity gradients. In this talk I will summarize our latest finding on the evolution of the metallicity gradients as a function of stellar mass, galaxy size and star formation efficiency up to z~2.5 in the EAGLE project. I will also show first results on a study of the processes that shape metallicity gradients with the CIELO simulations.
